Abstract

The invention belongs to the technical field of accelerants, and particularly relates to an alpha-methylstyrene accelerant as well as a preparation method and application thereof. The alpha-methyl styrene accelerant is prepared from the following raw materials in percentage by mass: 80 to 90 percent of alpha-methyl styrene and 10 to 20 percent of cobalt iso-octoate. The invention also provides a preparation method of the alpha-methyl styrene accelerant, which comprises the following steps: mixing the alpha-methyl styrene and the cobalt iso-octoate, and stirring for 30-60 minutes to obtain the alpha-methyl styrene accelerant. The method can reduce the exothermic peak temperature of a resin product, can effectively prevent the problems of cracking, deformation and the like of a thick product, and is suitable for preparing the artificial stone.

Description

technical field [0001] The invention relates to the technical field of accelerators, in particular to an alpha-methylstyrene accelerator and a preparation method and application thereof. Background technique [0002] Artificial stone is made of high molecular polymer, inorganic gelling agent or a mixture of the two as the bonding material, natural stone crushed (powder) material, aluminum hydroxide powder, etc. as the main raw materials, adding pigments and other auxiliary agents, stirring and mixing , coagulation and solidification and other processes processed stone. According to the different gel materials and functions used, artificial stone can be divided into resin type artificial stone, inorganic type artificial stone, functional artificial stone and so on. At present, the most widely used resin-based artificial stone is produced with unsaturated polyester resin as adhesive. [0003] Peroxide is added to the unsaturated polyester resin as an initiator / curing agent t...
